[Working Detail 29.09.11] Double-skin facade at the Museum Folkwang
The translucent facade consists of large, rectangular slabs made out of recycled glass. The silky matt, structured surface gives the facade an alabaster-like appearance and its colour shifts with the changing natural light.
The standard format of the slabs is approximately 2,780 x 1,240mm and the facade is based on a structural grid of 2.80 x 1.25m. The panels are suspended in front of the wall in landscape orientation. The horizontal joints are restrained as much as possible, while the vertical joints are articulated and expressed by means of continuous beading strips, 10-12cm wide, which are composed of the same glass ceramic material.
The expression of these joints relates more to the language of stone cladding than of glass, thus emphasising the ambivalence of the relationship between glass and stone.
The facade panels are supported by point fixings onto the wall construction, which are in turn restrained by the curtain walling mullions.
